Supra Owner's Manual_U (from Mar. '21 Prod.)
This chapter describes all stan-
dard, country-specific and
optional features offered with
the series. It also describes fea-
tures that are not necessarily
available in your vehicle, for
instance, due to the selected
options or country versions. This
also applies to safety-related
functions and systems. When
using these functions and sys-
tems, the applicable laws and
regulations must be observed.
Depending on the region, many
gas stations sell fuel that has
been customized to winter or
summer conditions. Fuel that is
available in winter,for instance
helps make a cold start easier.
For the best fuel efficiency, the
gasoline should be sulfur-free or
very low in sulfur content.
Fuels that are marked on the
gas pump as containing metal must not be used.
Fuels with a maximum ethanol
content of 25 %, i. e. E10 or
E25, may be used for refueling.
Ethanol should meet the follow-
ing quality standards:
US: ASTM 4806–xx
CAN: CGSB-3.511–xx
xx: comply with the current stan-
dard in each case.

The use of poor-quality fuels may
result in harmful engine deposits
or damage. Additionally, problems
relating to drivability, starting and
stalling, especially under certain
environmental conditions such as
high ambient temperature and
high altitude, may occur.
If drivability problems are encoun-
tered, we recommend switching
to a high quality gasoline brand
and a higher octane grade - AKI
number - for a few tank fills. To
avoid harmful engine deposits, it
is highly recommended to pur-
chase gasoline from Top Tier
retailers.
Failure to comply with these rec-
ommendations may result in the
need for unscheduled mainte-
nance.
